IMPRVEMENT IN DEVICES FOR SETTING BUTTON-HOOKS The Schedule" referredkto in these Letters Patent and making part of the same.

To all 'whom it 'may concern:

Be it known that I, JOHN S. PALMER, of Providence, in the county of Providence, and State OfRhode Island,`llave invented a new and useful Improved Tool for Setting Button-Hooks; and I do hereby declare that the following specification, taken in connection with tbe'drawings making a part of the saine, is a full, clear, and exact description thereof'.

Figure l is a side View.

Figure 2 is a face view of one of the jaws, showing the special improvement.

Figure 3 is a sectional' View.

The tool herein described is to beemployed in setting button-hooks,- used as a substitute for eyelets, to hold shoe-lacings.

It consists Ot'a pair ofJaws, A A', pivoted at a, and

worked by the lever-handles C C.

lOne of the jaws is fitted to grasp the button-hook while itis `being inserted, and the other carries the die-block, for bending and clinchin g its holdin g-prongs.

Into the face of one ofthe jaws A, a plate, B,is Iet in, and-so `arranged that it can be slid lengthwise, for a limited distance.

' The end of this jaw is eut ont, so as to leave it forked, and the sliding plate covers the space which Otherwise would exist.

The range of 'motion of the plate B is determined by the length of the slot b cut through it, and by the `screw-pin c, which stands in the slot, and enters the metai ofthe jaw beneath.

A thin plate, d, is placed over the sliding' plate B, which former is adjustable, and serves as a gauge for the button-ho0k, and also as a means for increasingr the friction upon the sliding plate, if the latter is too easily moved.

An aperture, c, is cui; through tbe sliding plate B, ot' suflicieut size to admit easily of the passage of the head of the button-hook, and the thickness ofthe plate is such, that when a button-hook is inserted in 'the aperture e, the plate will comfortably till the space between the head and the base of the prongs formed by the bend fin its neck, iig. 4.

To employ the tool for the purpose designed, the plate B is pulled forward, as in Iig. 2. The buttonhook is inserted from the under sideof the jaw, and hung upon the front edge of the aperture e, as seen in black 4at iig. 3. The plate is then to be pushed inward until .the button-hook brings up against the gaugeplated, figs. 1 and 3. The jaws are now brought tof gether, the leather, or other material to which the hook is to be attached, being heldover its points, as

in iig. 1.

The effect of bringing the jaws together is to cause the prongs of' the button-hook, which are project-ing upward, to prick through the material so held over them, and enter a conical cavity, g, in the fixed dieblock h, located upon the other jaw A', whereby the said prongs are bent inward.

The jaws are then allowed to open, and the material is pulled forward, which has the effect to slide outward the plate B, as in iig. 2. The jaws are now brought again together, and the prongs of the hook, in consequence of its change in position, will bringnp against the anvil-face of the'block h, as indicated in red line, fig. 3, and b e clinched down, as in iig. 4, a.

What I claim as my invention, and desire to secure by Letters Patent, isA

l. In combination with the jaws A A' andI fixed dieblock h., the sliding plate B, for holding the buttonhook, substantially asdescribed.

2. rlphe combination of the sliding plate B with the jaw A and the gauge-plate d, substantially as ldescribed.

JOHN S. PALMER.
